するため、ハンドルには錠前が収容固定されている。(Prior Art) As disclosed in Japanese Utility Model Publication No. 43-8300, the handle device for a door is formed by inserting an operation shaft projecting from the rear surface of the handle into a shaft cylinder part projecting from the rear surface of the seat. A lock plate fixed to the tip of the operation shaft is engaged with and disengaged from a receiving portion of the fixed frame body to lock and unlock the door with respect to the fixed frame body. A lock is housed and fixed on the handle to prevent the wheel from rotating.

するハンドルの錠止が解除される。An operation cam is projected at the tip of the rotor of the lock, and the operation cam is engaged with the passive hole of the lock body inserted through the diametrical hole of the operation shaft, and the key is inserted to fix the lock. After unlocking the rotor with respect to the main body, when the rotor is rotated in a predetermined direction, the tip end portion of the locking body escapes from the intermediate groove hole of the shaft tubular portion and retracts into the operation shaft, This unlocks the handle from the seat.

ればならないため、組立作業の能率が良くない。(Problems to be solved by the invention) However, in this conventional lock mechanism, when the lock body is inserted into the accommodation hole of the handle and fixed to the handle,
Since the engagement between the operation cam at the tip of the rotor and the passive hole of the lock member must be groped in the diametrical hole of the operation shaft which cannot be visually recognized, the efficiency of the assembling work is not good.

したりする恐れがある。When the handle is forcibly rotated without inserting the key in the locked state of the handle, bending stress is applied to the tip of the lock through the inner wall surface of the groove hole of the shaft cylinder.
Since the distance from the center of the operating shaft of the handle to the tip of the lock body is relatively short, the stress becomes large, and the lock body may be distorted or broken depending on the applied force and the manufacturing material.
There is a possibility that the operation shaft and the shaft cylinder portion that come into contact with the locking body may be locally deformed and deformed.

従って本考案の目的は、錠前機構の組立作業が能率良く

や故障を起すことなく、安定に作動するものである。When the handle 4 is forced to rotate in the door unlocking direction without inserting the key 7 in the locked state of the handle, bending stress is applied to the eccentric projection 10 via the inner wall surface 12c of the small arc-shaped groove 12. However, the small arcuate groove 12 is formed further outside the large arcuate groove 11 provided on the outer side of the shaft tube portion 3, and the eccentric projection 10 engaged with the tip portion 12b of the small arcuate groove 12 is formed. Since the distance between the centers of the operation shafts 5 of the handle 4 is set to be relatively long, the stress is small, and the eccentric projection 10 is broken or the disc 9 or the seat 2
There is no risk of local distortion or deformation. That is, the door handle device of the present invention operates stably for a long period of time without causing malfunction or failure.
